You probably want to check the virtual/linux-sources line /var/cache/edb/virtuals and /var/cache/edb/world to make sure that any old unused kernels aren't listed._________________Search | Read | Answer | Report | Strip

doesn't say exactly which kernel, I know that I have used gentoo-sources 2.4.22 and then all tje gentoo-dev-sources 2.6.x kernels..

Now I only use the latest 2.6.4..

What does this line say, should I edit it??

The gentoo-sources are the 2.4 series and the gentoo-dev-sources is the 2.6 series, so you should take out the gentoo-sources as you only use the 2.6 kernel._________________Search | Read | Answer | Report | Strip

Does unmerging an old kernel remove all traces of it? (besides /boot/*, of course)

What's the cleanest/best way to remove a kernel?

Unmerging only removes the last source tree you downloaded for that particular kernel. It also removes it from the "world" settings so it won't try to emerge again next time you emerge -U world.

The best way to get rid of unused kernel sources is to unmerge it, then rm -rf the remaining (older) versions of that kernel source._________________Gentoo...it's like wiping your ass with silk. Or sandpaper.
